Firmware updates on the aforementioned UPS models are slow, and Internet Explorer has a timeout based on rate of transfer during uploading. This timeout varies between versions, within the same version, even for operations defined to have no timeout. No other browser Schneider Electric has tested including Firefox, Chrome, Safari, and Opera behaves this way.

Resolution

It is recommended not to use Internet Explorer for UPS firmware upgrades via the Network Management Card. Use the FTP method (outlined in knowledge base article ID FA170679) or any other web browser. Schneider Electric is evaluating possible remedies to support Internet Explorer in the future for the UPS firmware upgrade via AP9630/31.
